itemMapping trigger output format

For context, I am creating a template that looks like;
When a new item is created in board, create a task in reminders and sync all future updates.

For this I need to create a trigger;
When a new item in board is created in monday.com

  • This trigger will create webhooks to for item creation and column updates
    And a new action;
    create a task in reminders and sync all future updates.
  • This will create the task in the external app

I would like to map an item in monday.com to a task in the external app. Currently I am having my trigger output an itemMapping and setting this as the source entity of the task in the action. I suspect the format of the itemMapping is incorrect though as the task data is not being populated when it is passed to the action. Ideally i’d like to output an itemValues object from the trigger, however this does not seem to be an option currently.

I’d like to know what the format of the itemMapping entity should be so I can output it correctly.

Thanks!
